Popping sounds in your ductwork can be caused by movement in the ducts when airflow causes a sudden temperature change. This can be a sign that your duct system is undersized for your home.

An undersized duct system can also cause issues such as leaky ducts and reduced airflow. This can lead to mold growth and decreased indoor air quality.

There are numerous possible causes why your A/C system can freeze, such as insufficient airflow, dirty evaporator coils, low refrigerant level, motor malfunction, or blocked vents and registers, among others.
